FOUNTAIN PEN.

yApplication filed November 25, 1924. Serial No. 752,109.

To all whom t may concern:

Be it known that I, STORMONT JossELYN, of Atlantic, in the county of Norfolk and State of Massachusetts, a citizen of theY United States, have invented a new and useful improvement in Fountain Pens, of which the following is a full, clear, and exact description, reference being had to the ac-l companying drawings, forming a part of this specication, in explaining its nature.

The invention relates to that type of fountain pens having a barrel and Within 1t a collapsible ink-containing sack and, associated with this sack, mechanism for collapsing it and otherwise permitting of its eX- pansion and consisting` in part of a presser bar and a lever for actuating this bar.

Among the objects of the invention are to provide means which will ensure accurate positioning of the presser bar inside the barrel with relation to the lever when the parts are assembled; also, to provide an improved means possessing special advantages for retaining the lever and holding it in an outof the-way position when not in use.

The invention can best be seen and understood by reference to the drawings in vvhich-u Figure 1 is a longitudinal cross vertical section of a fountain pen embodying the invention.

Fig. 2 is a section in enarged detail of the inner end portion of the barrel to the pen and certain associated parts to which reference Will later be made.

Fig. 3 is an elevation of the inner end of the barrel.

Fig. a is a cress section on the line 1 -4c of Fig. 2.

Fig. 5 is an enlarged detail partly in side elevation and partly in section of the outer end portion of the barrel with associated parts, the lever, to which special reference Will be made, occupying its down-turned, outoftheway position and the end piece of the barrels secured thereto and Fig. 6 is the same as F ig. 5 excepting that the end piece to the barrel is shown disconnected therefrom and the lever occupying an operative position.

1 represents the barrel of the pen. 2 is the pen-carrying section having a neck portion 3 whichfits, preferably slidably, within the forward end of the barrel. The neck portion 3 has an extension l of aslightly less diameter-and over this is fitted the end of a collapsible ink-carrying sack 5' which lies within the chamber of the barrel. 6 is a presser bar for collapsing the sack. This bar is disposed within the barrel over the sack, contacting with it, and extends in longitudinal alignment therewith. 7 is a lever lying within a longitudinal slot S in the barrel. It is by means of this lever as it is turned that the presser bar is actuated or moved down to compress the sack. The lever is arranged to turn on a fulcrum which comprises a ring 9 passed through the lever and lying within an annular groove 1() formed in the interior wall of the barrel.

The pressel` bar 6 is attached by a fastening or pin 11 at about the middle of its eX tension to the inner end of a spring bar 12, both bars being in alignment. The spring bar is retained within the barrel by a holder 13. This comprises an internal sleeve which fits snugly within the barrel and to which the outer ends of the spring bar is secured and this preferably by integral connection, the holder being formed by curved wings extending laterally from the bar on either side thereof. The holder is also provided with a struck-up or projecting portion 14 which fits within a groove 15 in the interior Wall of the barrel. This groove extends from the inner end of the barrel and in a direction in precise alignment with the lever 7 and presser bar 6 actuated by it. The projection 14: from the holder, thus iitting in the groove l5, prevents lateral displacement or turning of the holder when once positioned within the barrel. It also insures absolute and accurate setting of the holder within the barrel so that the spring bar and presser bar attached to it will occupy a position where the lever when actuated, will have positive and accurate engagement with the presser bar bar for compressing the sack. In the assemblage of the parts the holder 13 carrying the spring bar with presser bar attached to it is inserted through the open inner end of the barrel and the holder can only be inserted within the barrel when the pro jection 14 thereon is contained Within the groove 15 in the barrel, the holder being slid into place with the projection thereof sliding along the groove. When located within the barrel the holder will occupy a posi-- tion where it will fit around the extension l of the pen-carrying section. In the assemblage of the parts the ho-lder is first inserted and afterward the pen-carrying section 1s pressed into place, the extension l to the neck thereof then fitting Within the holder.

The lever 7 fulcrumed to turn on the ring 9 for actuating the presser bar, as previously noted, comprises a Work arm 16 which engages the presser bar as the lever is turned and an operating arm l? for turning the lever. The lever occupies a downturned out-of-the-w-ay position lying Within the slot in the barrel, as previously noted, When the lever is not in use. The barrel is provided With a closed outer end Wall 18 and the slot 8 Within which the lever lies extends not only to the outer end of the barrel but also across the end Wall i8 to the centre of this Wall. The operating arm of the lever has a bend or offset 19 in it by which the arm, When the lever lies recessed Within the slot '8, extends to the centre of the end Wall 118 to the bar-rel and thence extends by a portion 2() beyond the end of the barrel in central alignment therewith. On the portion 20 lof the operating arm thus extending is arranged an end .piece 2l for the barrel. This end piece has threaded connection with the barrel in extension of the barrel. For the rpurpose of providing such connection the end Wall 18 of the barrel is provided With an internally-threaded projection or boss 22 of less diameter than the end Wall and centrally disposed. The inner part of the end piece 2l which faces the louter end of the barrel is provided with a threaded socket 23 by which it maj,V ltit over and :have threaded connection with the projection or boss 22 on the end of the imrrel and thereby become attached to the barrel, the end piece vvhen tightened bearing against the end Wall of the barrel when the end piece Will assume -a position in lproper and Iprecise alignment with the barrel in extension thereof. The end 2O of the operating lever projects lthrough the socket 52? in the end piece and thence, preferably rather loosely, through a partition 24E formed Within the end .piece beyond the socket and which forms the bottom of the socket. Beyond the 1partition`2l the end piece is provided with a `socket 25 into which 4the end of the lever arm projects and Where it is .provided With a head 26 preferably obtained `by upsetting the metal from which the lever is made. rll-ie head 26 is'larger*diametrically than fthe opening through the partition. 24T 'and the end piece is accordingly prevented from falling'or being drawn from the end of the lever especially When lthe end piece is Unthreaded yfrom the end of the barrel to permit turning of the lever as shovvn in Fig. (i. The head 26 on the end of the operating lever is formed after the vend of the lever has I.been passed lthrough the partition 2a, and the arrangement ofthe parts should be such that the head should have sufficient freedom of movement Within the socket 25 to permit of the unserevving of the end piece extending from its inner fend an appreciable.
